Gantt Chart Maker
Gantt charts with MCP & AI
Connect an AI assistant to Gantt Chart Maker over the Model Context Protocol and build, edit and export real project plans just by chatting — no API keys, nothing to install.
Gantt Chart Maker runs a hosted MCP server. That means an AI assistant can plan a project for you — create a chart, add tasks, link dependencies, then hand you a real, editable Gantt chart you own — instead of pasting a picture into the chat.
What is MCP?
The Model Context Protocol (MCP) is an open standard that lets AI assistants securely call outside tools. Gantt Chart Maker exposes its charts through MCP, so any MCP-capable assistant can read and edit them on your behalf — using your own account, over a browser sign-in, with no key or secret to copy.
Which assistants work?
Claude (Desktop, Claude Code and claude.ai), ChatGPT (Developer Mode, paid plans) and Grok (Connectors, paid plans) connect as MCP clients today. Composer connects through Grok Build, xAI's coding CLI. DeepSeek depends on whether the app you run it in supports custom MCP connectors; where it doesn't, you can still have it draft a plan and import it in seconds. The guides below cover each case honestly.

Do I need an account?
Yes — charts are saved to your Gantt Chart Maker account, and the MCP connection signs in as you. The editor itself is free and needs no account; only the AI connection does.
Is it safe?
The connection uses OAuth with the same provider you already use (Google, GitHub or Microsoft). The assistant only touches charts you own or collaborate on, and never gets a password or API key.
Does it cost anything?
Gantt Chart Maker is free. You just need your AI assistant of choice; any MCP fees are on that side, not ours.
